Abstract

The utility model relates to an improved structure of a lighting source, belonging to the electromechanical category. It is composed of a light guide plate and a light emitting element, wherein the light emitting element is arranged at the side edge of the light guide plate, and when the light emitting element emits light, the light guide plate is evenly illuminated, and the light received by the light emitting element is emitted. The advantages are: it consumes less power and has a power saving effect; the heat energy generated during use is lower; the light is softer and feels comfortable during use; it contains less toxic chemical components and is more environmentally friendly; the shape and size are not restricted, the variability is large, the compatibility is high, and the practicability is strong.

Description

The lighting light source structure improvement

Technical field

The utility model relates to electrical category, particularly a kind of lighting light source structure improvement.

Background technology

Shown in accompanying drawing 1 and accompanying drawing 2, general lighting apparatus commonly used, it reaches the effect of illumination by bulb A or fluorescent tube B, but this bulb A or fluorescent tube B are a scattering and uneven area source, and can't do the control of a directionality for light, under long-time the use, easily wavelength difference and the light angle because of light produces discomfort; In addition, bulb A or fluorescent tube B that this is commonly used, its inside contains poisonous chemical substance, abandons the back and easily produces environmental issue, need be improved.

The utility model content

The purpose of this utility model is to provide a kind of lighting light source structure improvement, solved that lighting apparatus consumed power commonly used is big, the expense electricity, the heat energy that distributes during use is bigger, uses uncomfortable for a long time, and contain and poison composition, easily cause problems such as environmental pollution.

The technical solution of the utility model is: light supply apparatus is made of LGP and light-emitting component, wherein, be provided with light-emitting component, when light-emitting component is luminous, make LGP evenly be subjected to light at the lateral margin of LGP, and the light that will be received in light-emitting component penetrates, and makes it reach required illumination functions; Light supply apparatus can be provided with heat abstractor and make the light-emitting component efficiently radiates heat, and this light supply apparatus can be located at desk lamp, indicator lamp, daylight light fixture and relevant as on the lighting; Light-emitting component can be made as fluorescent tube, bulb, light-emittingdiode and relevant element with luminous efficacy; Can be in a side device reflector plate of LGP, to strengthen its illuminance; Can its light more evenly be mixed in a side device diffusion sheet, the brightening piece of LGP, make light softer.

Advantage of the present utility model is: consume smaller power, the tool power saving effect; The heat energy that is produced during use is lower; Light is softer, feels comfortably cool during use; Contain and poison that to learn composition low, comparatively environmental protection; The shape size is unrestricted, and variability is big, compatibility is high, and is practical.
